Stoimen - thanks for getting back to me.

I'm loading several thousand items into a XamDataTree. The data tree is contained in a grid. the grid is contained in an igDock:ContentPane. The tree is initially collapsed. When I expand it, I don't automatically get a vertical or horizontal scroll bar, even though both should show up.

Hi,

I tested, but I was unable to reproduce your issue. I tried something like the following:

<igDock:XamDockManager>
        <igDock:XamDockManager.Panes>
            <igDock:SplitPane>
                <igDock:ContentPane Header="foo">
                    <Grid x:Name="LayoutRoot" Background="White">
                        <Grid.Resources>
                            <data:TestDataSource x:Key="TestDataSource"/>
                        </Grid.Resources>                        <ig:XamDataTree x:Name="TestXamDataTree"
                        ItemsSource="{StaticResource TestDataSource}">
                            <ig:XamDataTree.GlobalNodeLayouts>
                                <ig:NodeLayout Key="EnumerableData" TargetTypeName="TestData" DisplayMemberPath="TextData" IsDraggable="True"/>
                            </ig:XamDataTree.GlobalNodeLayouts>
                        </ig:XamDataTree>
                    </Grid>
                </igDock:ContentPane>
            </igDock:SplitPane>
        </igDock:XamDockManager.Panes>
    </igDock:XamDockManager>

Could you please try to isolate the issue in a separate sample and send it so I am able to reproduce your issue? Also, please let me know which is the build you are using (1003, 2018?).

Thanks,

Hi Stoimen. thanks for sticking with me. I think I figured out the problem.

We are using Prism.

With this in the shell, I do not get scroll bars on the tree in my view. Actually I was able to by adding row/column defs in the view xaml with the row having a fixed height.

<igDock:ContentPane x:Name="baseTaxonomyDock" Header="Base Taxonomy" AllowClose="False" CloseButtonVisibility="Collapsed" IsPinned="True">
 <ItemsControl prism:RegionManager.RegionName="BaseTaxonomyRegion" DockPanel.Dock="Right"/>
</igDock:ContentPane>

With this in the shell, I do get scroll bars on the tree in my view. No row/column defs needed. It just works.

<igDock:ContentPane x:Name="baseTaxonomyDock" Header="Base Taxonomy" AllowClose="False" CloseButtonVisibility="Collapsed" IsPinned="True">
 <ContentControl prism:RegionManager.RegionName="BaseTaxonomyRegion" DockPanel.Dock="Right"/>
</igDock:ContentPane>
